摘　　要：我国许多建设年代久远的小型水库存在众多安全隐患,急需进行除险加固。针对树山水库所面临的结构稳定,洪水排泄,渗流安全等问题,通过对水库的土石坝坝体进行修正,采取坡面防护、重建大坝排水棱体等工程措施,对土石坝进行加固。对威胁大坝安全的溢洪道采取水泥砂浆加固措施并重建输水涵管取水口,顺利解决了水库所面临的问题。计算分析除险加固后的土石坝渗流安全性,均满足渗流稳定性要求,除险加固工程任务成功实现。Many small reservoirs with a long history of construction in China have many potential safety hazards,so it is urgent to carry out risk removal and reinforcement. In view of the problems faced by Shushan Reservoir such as structural stability, flood discharge and seepage safety, the earth-rock dam body of the reservoir is corrected, slope protection and reconstruction of prism of dam drainage are adopted to reinforce the earth-rock dam. Cement mortar reinforcing measures are taken for Spillway threatening dam safety and water intake of water conveyance culvert is reconstructed, which smoothly solves the problems faced by reservoir. The seepage safety of earth-rock dam after danger removal and reinforcement is calculated and analyzed, which meets the requirement of seepage stability and the task of danger removal and reinforcement is successfully realized.
